Data logger capable of 122 hours of data acquisition, averaging, and storage.
Rechargeable battery allowing up to 8 hours of operation.

Principle of Operation:

The RA-915M operates using Differential Zeeman atomic absorption spectrometry with high-frequency modulation of light polarization (ZAAS-HFM).

Applications:

Background air monitoring and mercury surveys.
Indoor and outdoor pollution detection and mapping.
Demericurization control and occupational health and safety.
Geochemical exploration.
Complies with EN 15852 standard for total gaseous mercury determination in air.

Warranty and Service:

The RA-915M analyzer and its attachments come with a full 1-year warranty. Installation and commissioning can be performed on-site by service engineers or certified distributors.

Delivery Set:

The RA-915M is supplied with RAPID software, charger, shoulder bag, air intake hose, spare filters, interface cable, and manuals. Additional attachments are available upon request.
